Join me for an inspection of a waffle slab before it is poured.
Check out our inspection of this waffle slab before it is poured. Give it a thumbs up if you’d like to know the 10 most important things to look for when inspecting a waffle slab.
What are the Components of a Waffle Slab?
I had an enquiry the other day.
“What materials are used to build a waffle foundation?”
The materials used to build are waffle foundation are:
- Black plastic. This is the damp proof membrane that stops moisture rising out of the ground and into a house.
- Waffle pods. These are polystyrene blocks used to hold the concrete in place until it cures. The deeper the pods the stiffer the waffle slab.
- Steel reinforcement bars. Steel reinfrocement bars run in the bottom of the ribs and are the ‘bottom reinforcement’.
- Steel slab mesh. Steel wires welded into a fabric are placed on top of the waffle pods. These are the top reinforcement of the slab.
- Temporary formwork. Timber or aluminium formwork makes the sides of the waffle pod slab until the concrete is strong enough to stand up lby itself.
